Detailed introduction
The new Yokogawa EJA430E high-performance pressure transmitter (traditional installation) is a traditional installation type high-performance gauge pressure transmitter under the Yokogawa EJA transmitter - E series. It uses globally advanced single crystal silicon resonant sensor technology, capable of converting measured pressure into a 4~20mA DC current signal output, featuring fast response, remote setting monitoring, and self-diagnosis functions. It is widely used for measuring the pressure of liquids, gases, or steam and can be used with communication protocols such as HART 5/7, 1 to 5V HART 7 (low power), FOUNDATION fieldbus, PROFIBUS PA, or BRAIN.
The E series of EJA transmitters is the latest DPharp series launched by Yokogawa Electric. It was released in 2012, combining the robustness and success of the EJA-E series products with the performance of the pure EJX-A series, providing the type of product expected from Yokogawa Electric. Its compact design and the stability provided by robust materials have reached the expected level of Yokogawa Electric products. The Yokogawa EJA430E high-performance pressure transmitter (traditional installation) is our traditional installation pressure transmitter and is the upgraded model of the EJA430A pressure transmitter.
